In most faculties, the courses numbered 100–199 are primarily for first-year students, those numbered 200–299 are primarily for second-year students; similarly 300–399 for third-year students and 400–499 for fourth-year students. Courses numbered 500 and above are considered graduate-level, and are only available to undergraduates by permission of the departments concerned. Where faculties have a different style of classification of courses, the level of study is indicated in the description of their study programs.
In the course descriptions, the credit value of a course, where given, is shown in parentheses following the course number. In general, 1 credit represents one hour of instruction or two to three hours of laboratory work per week throughout one term of a Winter Session (September to December or January to May). A credit is approximately one semester hour.
Some courses are listed with a choice of credit value; the form: (2–6) implies that the course may be given for any number of credits from 2 to 6 inclusive; the form: (2/6) implies that the course will be given either for 2 credits or 6 credits.
Where the parentheses are followed immediately by "c", the credit value of the course will be determined by the student in consultation with the department offering the course. Where the parentheses are followed immediately by "d", the credit value of the course in any particular session will be determined by the department offering the course.
In all cases, the maximum credit value is that which may be obtained by a student during the complete program of study (i.e., it is not the maximum for a given year).
If specific studies are required as background to a certain course, they are notated as such in the course description. A prerequisite is a course that the student must have completed prior to registering for the selected course. A corequisite is a course that the student must take prior to or concurrently with the selected course. In some instances, prerequisites and corequisites may be waived at the discretion of the instructor. General prerequisites that apply to all courses in a list are frequently given just before the list. In a dispute over the adequacy of prerequisites, the course instructor will make the decision. In all cases where prerequisites are indicated, the implication is "or the equivalent" and "or the consent of the instructor."
An equivalent course indicates that it is a duplicate of the course selected.
Some courses offered as special topics are on offer as pilot programs for material that is later incorporated into permanent courses. In such instances where a special topic and permanent course substantially duplicate material, only one of the special topic or permanent course may be taken for credit.
The number of hours assigned each week to lectures (first digit) and to laboratories (second digit) are shown in square brackets at the end of a course description. Where a third digit appears, it refers to periods where discussions, tutorials, or assigned problems are done. An asterisk (*) indicates alternate weeks. The first set of digits refers to the first term (September to December) and the second set to the second term (January to May); when only one set is given, it means either term. Graduate courses and courses in some faculties are not so designated.
Not all courses listed are offered each year. Most courses offered in a Winter Session, as well as places and times of class meeting and names of instructors, appear in the online Course Schedule. For those courses not so listed, contact the department concerned.
